BACKGROUND OF THE INVENTION

The proliferation of electronic and electrical devices is a key factor fueling an ever-increasing demand for additional alternating current (AC) outlets at home, on the road, and in the workplace. Often there are too many devices and not enough outlets. Additionally, devices including calculators, phones, and laptops use AC to direct current (DC) power converters (commonly called wall-bricks) to connect to AC power outlets. Due to their non-standard bulky form-factors, wall-bricks often take up more than one outlet, exacerbating outlet-shortage problems and driving users to seek solutions.

A popular remedy is to use multi-outlet power strips. However, these power strips provide an ineffective solution because they fail to adequately address all of the problems created by, and associated with, the increasing prevalence and use of wall-bricks.

For example, a user who owns six devices buys a power strip. While connecting the equipment, the user realizes that two devices use wall-bricks. Upon plugging the bricks into the power strip, the user discovers that only two or three of the six outlets remain open, leaving at least one outlet short. After spending $25-$200, the user expected to be able to use all the outlets, but now must buy one or more additional power strips to plug-in the remaining devices.

Low-cost power strips provide additional outlets, but do not adequately condition or stabilize incoming power, increasing the risk of equipment malfunction or outright failure. Moderate to high priced surge protectors perform well, but bulky wall-bricks often cover multiple outlets, reducing the number of devices that can be connected.

Additionally, wall-bricks often generate heat and electrical interference in addition to passing along the ambient AC conducted sags, spikes, surges, and noise generated by the power-grid and carried along AC power-lines throughout industrial, office, and residential settings. Electrical power disturbance events cause data loss and damage equipment. Wall-bricks pack and travel poorly, create cable-clutter, and are an eyesore.

Damaged equipment and downtime costs are a growing concern among users. As technology has advanced, business, commerce, home, and industrial users have become increasingly dependant on the health of the networks that supply and manipulate data and information. Additionally, the growing emphasis on network speed and the sheer volume of transactions that can take place in a fraction of a second make the prospect of downtime that much more ominous. The cost to business and industry of human or naturally caused power surges and outages has become substantially more detrimental.

It is clear from the statistical evidence that power conditioning is a vital issue and one whose importance is only going to increase. Clean, constant, noise-free power is required to ensure the proper operation, and to protect the delicate circuitry, of today's electronic and electrical devices.

Presently, systems and methods are needed that simultaneously solve outlet-shortage and transient voltage surge and noise problems. New systems and methods are needed to eliminate wall-brick issues and other identified problems.

DETAILED DESCRIPTION

The automatic sensing power systems and methods enable alternating current (AC) to direct current (DC) power conversion, DC to DC power conversion and supply, data communication, and power management. In one embodiment, an automatic sensing power system (ASPS) component is embedded in an electronic device, such as a laptop computer, and a power delivery component resides in an ASPS, such as a power strip or a receptacle.

In one embodiment, upon connection to the ASPS, the electronic device communicates its power requirements to the ASPS via a power cord or plug. The ASPS processes the request and supplies the appropriate power. Inexpensive low voltage electrical cords and modular adapters replace the wall-bricks typically supplied with cell and desk phones, personal digital assistants (PDAs), computers, mobile phones, digital cameras, cordless drills, fax machines, and other electrical devices. The ASPS is programmable and upgradeable.

In another embodiment, the ASPS enables a user to enter a power level for an electronic device. The ASPS supplies the appropriate power.

In another embodiment, the ASPS has a voltage sampling system that samples the power levels required by an electrical device. The ASPS processes the sampled voltage and supplies the appropriate power.

The ASPS solves many problems currently encountered by home, office, and industrial consumers. The ASPS couples with single and multi-receptacle plug-in and hard-wired surge suppression devices, AC/DC power converters and transformers, and a wide-range of electronic and electrical appliances, tools, and devices.

In one embodiment, the ASPS eliminates wall-bricks by placing modular DC receptacles in a power system. The power system has AC and DC receptacles in one unit, thereby eliminating the need for multiple power strips. In some embodiments, the power system includes communication and networking interfaces and systems over which communications may be transmitted, such as through Bluetooth, Ethernet, Firewire, USB, and/or other connections. In this embodiment, the ASPS includes expanded data line protection, such as for cable, DSL, Ethernet, and modem protection. In another embodiment, the ASPS integrates gateway, network, and router capabilities. Another embodiment incorporates data communication over a broadband connection. In one example, electronic devices communicate with and through the power system via a DC connector or an AC connector.

In another embodiment, the ASPS includes a line-cord or plug device with a detachable wall plug device. Once detached, the wall plug device can be moved between rooms or offices or taken on the road to replace wall-bricks. In some examples, the detachable wall plug device includes a voltage sampling system.

FIGS. 1-3 depict an exemplary embodiment of an automatic sensing power system (ASPS). In the embodiment of FIG. 1, the ASPS 102 includes a line-cord device 104 and a detachable wall plug device 106. The line-cord device 104 has a housing 108, and the detachable wall plug device 106 has a housing 110. In other embodiments, the ASPS 102 may be only a wall plug device, only a line-cord device, or a combination thereof. The ASPS 102 also may be embodied in other forms, such as a modular wall plug permanently installed or removably installed in place of a wall receptacle, an alternating current (AC) wall receptacle, or another AC or direct current (DC) device.

The ASPS 102 may be incorporated in, for example, an electronic device, such as a computer, a laptop computer, a pocket PC, a personal digital assistant (PDA), a mobile phone, a recording device, or another electrical device. As used herein, an electrical device means a device that operates using electricity, including AC and/or DC electricity. Similarly, electrical devices may use a portion of the ASPS systems identified below, including those electrical devices previously listed and other electrical devices.

Referring again to FIGS. 1-3, the line-cord device 104 includes one or more AC receptacles 112-126. Each AC receptacle 112-126 includes a power control/indicator 128-142, such as a physical or logical on/off switch used to enable or disable power flow to the associated AC receptacle 112-126. In one embodiment, the power control/indicators 128-142 are lighted switches. In another embodiment, the lighted switches are lighted when power is enabled to the AC receptacle, and not lighted when power is not enabled to the receptacle. In another embodiment, the power control/indicator 128-142 is only an indicator, such as a light, and is not used to enable or disable power to the associated receptacle 112-126. For example, a processor within the ASPS 102 may be used to enable or disable power to a receptacle, and the power control/indicator 128-142 indicates whether or not power is enabled or disabled for that receptacle. In still another embodiment, the power control/indicator 128-142 is configured to enable and disable power to the associated receptacle, and the power control/indicator includes an indicator, such as a light, to indicate whether power is enabled for the receptacle either by the physical power control or by a processor or other system or method.

The AS DC receptacles 144-148 also have an associated power control/indicator 150-154 such as a physical or logical on/off switch used to enable or disable power flow to the associated DC receptacle 144-148. In one embodiment, the power/control indicators 150-154 are lighted switches. In another embodiment, the lighted switches are lighted when power is enabled to the DC receptacle, and not lighted when power is not enabled to the receptacle. In another embodiment, the power control/indicator 150-154 is only an indicator, such as a light, and is not used to enable or disable power to the associated receptacle 144-148. For example, a processor within the ASPS 102 may be used to enable or disable power to a receptacle, and the power control/indicator 150-154 depicts whether or not power is enabled or disabled for that receptacle. In still another embodiment, the power control/indicator 150-154 is configured to enable and disable power to the associated receptacle, and the power control/indicator includes an indicator, such as a light, to indicate whether power is enabled for the receptacle either by the physical power control or by a processor or another system or method.

In the embodiment of FIGS. 1-3, the line-cord device 104 also has a main power control/indicator 156. The main power control/indicator 156 is used to enable or disable power to the line-cord device 104.

The data communication port 170 is used to communicate process data, control data, control instructions, update data, electrical device data, and other data with a processing device, a computing device, or another device. In one embodiment, the data communication port 170 is a universal serial bus (USB) port.

In another embodiment, other data communication connectors may be used. As best depicted in FIGS. 1 and 3, other data communication connections 172 and 174 are used to communicate data to and from the ASPS 102 in various formats and using various protocols. In one example, the data connections 172-174 include one or more cable ports, such as an in and out cable connection. Other types of data connections, networking connections, device connections, and/or device controllers may be used.

Referring again to FIGS. 1 and 2, the detachable wall plug device 106 includes AS DC receptacles 176-180. The AS DC receptacles 176-180 have an associated power control/indicator 182-186. The AS DC receptacles 176-180 and the power control/indicators 182-186 are the same as those described above.

The detachable wall plug device 106 also includes one or more electrical connectors 188-190, such as module plugs, used to transfer power to the wall plug device. The electrical connectors 188-190 connect to receiving connectors 192-194 in the line-cord device 104. AC and/or DC power is transmitted from the line-cord device 104 to the wall plug device 106 via the electrical connectors 188-190 and the receiving connectors 192-194. In some embodiments, communications, including control instructions and/or data, are transmitted from the line-cord device 104 to the wall plug device 106 via the electrical connectors 188-190 and the receiving connectors 192-194. It will be appreciated that one or more electrical connectors may be used. Additionally, while a standard 3-prong wall plug is depicted in FIGS. 1 and 2, other electrical connectors may be used.

In one embodiment, the wall plug device 106 includes a fuse device. In another embodiment, the wall plug device 106 includes a surge protection device and/or other voltage and/or amperage protection devices. In another embodiment, the wall plug device 106 includes a reset control.

In one embodiment, the ASPS 102 includes a grounded indicator 196 and/or a protected indicator 198. The grounded indicator 196 indicates that the ASPS 102 is properly grounded to an electrical supply, such as to an AC receptacle. Therefore, the ASPS 102 should provide properly grounded electrical connections for electrical devices connected to the ASPS.

The ASPS 102 also may include a protected indicator 196 in other embodiments. The protected indicator 198 indicates that surge protection and/or noise filtration systems and/or circuits are functional.

FIG. 5 depicts an exemplary embodiment of an automatic power system (APS). The APS 502 of FIG. 5 includes an automatic sensing power system (ASPS) 102B, an electrical supply 504, an electrical device 506, and a computing device 508. The ASPS 102B is used to automatically determine the power requirements of the electrical device 506, including voltage and/or amperage requirements, and supply the appropriate power to the electrical device.

In this embodiment, the electrical device 506 does not have a power converter. Instead, the electrical device 506 includes a simple electrical connector between the ASPS 102B and the electrical device. The electrical connector is not a bulky power converter, such as a wall brick. The connector may be a standard power conducting wire, such as those used for a laptop computer, a PDA, a mobile telephone, or another electrical device (without the power converter).

The ASPS 102B receives power from the electrical supply 504. Upon determining the power requirements, the ASPS 102B supplies the correct power to the electrical device 506.

The ASPS 102B is configured to sample power from the electrical device 506 to determine the power requirements for the electrical device. In one example, the ASPS 102B is configured to sample voltage from the electrical device 506 to determine the power requirements of the electrical device. In another example, the electrical device plugs into the ASPS 102B. The ASPS 102B then determines the power requirements for the electrical device by sampling the voltage and/or current used by the electrical device. In another example, the electrical device plugs into the ASPS 102B, and the ASPS determines the power drawn by the electrical device.

In one embodiment, the ASPS 102B includes a receptacle to which the electrical device 506 plugs or otherwise connects. In another example, the AC plug of the transformer (i.e. wall brick) for the electrical device 506 is plugged into an AC power sampling receptacle of the ASPS 102B, and the ASPS 102B determines the power used to drive the transformer. In another example, the AC plug of the transformer (i.e. wall brick) for the electrical device 506 is plugged into an AC power sampling receptacle of the ASPS 102B, and the ASPS 102B determines the power output from the transformer. In another example, the DC end of the transformer (i.e. wall brick) for the electrical device 506 is plugged into a DC power sampling receptacle of the ASPS 102B, and the ASPS determines the power output from the transformer. In another example, a power connection is connected between the electrical device 506 and a connector for the ASPS 102B, and the ASPS determines the power that will be drawn by the electrical device.

In another example, the ASPS 102B comprises a voltage sampling system that determines the voltage drawn by the transformer, output from the transformer, or drawn by the electrical device. In another example, the ASPS 102B comprises a voltage sampling system that determines the voltage generated by the transformer or electrical device.

The ASPS 102B communicates with the computing device 508. The computing device 508 may be a computing device, data device, or another device configured to communicate with the ASPS 102B.

In one embodiment, the computing device 508 receives status data from the ASPS 102B, including faults, breakdowns in processes, if any, surge identifications, identification of sampled voltage, and other status information. In another embodiment, the ASPS 102B receives data from the computing device 508. In one example, the ASPS 102B receives control data, such as configuration data, from the computing device 508.

In one example, a user uses the computing device 508 to load the power requirements of the electrical device 506 to the ASPS 102B. The ASPS 102B stores the power requirements and uses the power requirements to provide the appropriate power levels, including voltage and/or amperage levels, to the electrical device 506.

In another example, the ASPS 102B receives data from the computing device 508. The computing device 508 is configured to transmit power requirements for the electrical device 506 to the ASPS 102B. In this example, the ASPS 102B is configured to assign a particular receptacle, such as a particular DC receptacle or a particular AC receptacle, to the electrical device 506. In this example, a user may plug the electrical device 506 into a particular receptacle in the ASPS 102B, and the power requirements will be transmitted to the electrical device 506.

In one example, the computing device 508 is configured to enable the particular receptacle for the electrical device 506. In this example, the computing device 508 also is configured to disable one or more other receptacles, including one or more other AC receptacles and/or DC receptacles. In this example, disabling one or more receptacles provides a safety feature so that the electrical device 506 is not inadvertently plugged into a receptacle with the wrong power requirements, which may result in damaging the electrical device. In this example, an indicator light may indicate whether the receptacle is enabled or disabled to receive power and/or to transmit power to an electrical device.

The ASPS 102B may receive configuration data and/or control data to configure one or more receptacles. For example, the ASPS 102B may configure a first receptacle for a mobile telephone and a second receptacle for a computer. In this example, the first receptacle would provide the correct power requirements to the mobile telephone, and the second receptacle would provide the correct power requirements to the computer.

In the above example, the electrical device 506 does not require an AS processing system, as described more completely below. This embodiment provides flexibility to the user for devices not having the AS processing system.

It will be appreciated that the configuration data and/or control data may be provided to the ASPS 102B in a variety of ways. In one embodiment, the ASPS 102B receives configuration data identifying a model of a particular electrical device 506, such as a device name and/or a model name or number or another identifier. In this example, data identifying particular electrical devices and their power requirements reside on the ASPS 102B. In this example, the ASPS 102B performs a search, look up, or other process to identify the particular electronic device model and its power requirements from the data stored on the ASPS. The ASPS 102B then can provide the correct power to the electrical device 506.

In another embodiment, the ASPS 102B is configured to receive the particular power requirements, including voltage and/or amperage requirements, directly from the computing device 508. In this example, the ASPS 102B is not required to perform a search, look up, or other processing operation to identify a particular electrical device's power requirements. In this example, after receiving the configuration information, the ASPS 102B configures a particular receptacle for the power requirements.

In another example, the ASPS 102B includes a power sampling connection, such as a power sampling receptacle, a power connector, or other connection. The electrical device connects to the ASPS 102B. The ASPS 102B samples the power required by the electrical device 508, including the voltage requirements and/or current requirements. The ASPS 102B transmits an identification of the sampled power requirements to the computing device 506. The computing device 508 assigns a particular receptacle, such as a particular DC receptacle, to the electrical device 506 for that sampled power. The ASPS 102B assigns the sampled power to the assigned receptacle. In this example, a user may plug the electrical device 506 into a particular receptacle in the ASPS 102B, and the power requirements will be generated to the particular receptacle for the electrical device 506.

In one example, the computing device 508 is configured to enable the particular DC receptacle to which the sampled power requirements will be generated for the electrical device 506. In this example, the computing device 508 also is configured to disable one or more other receptacles. The computing device 508 may select or assign one or more receptacles for one or more sampled power requirements. In this example, an indicator light may indicate whether the receptacle is enabled or disabled to receive power and/or to transmit power to an electrical device.

In another example, the ASPS 102B is configured to automatically sample the power requirements for an electrical device 508. In one example, the ASPS 102B has a detector to detect when an electrical device 508 is connected to the ASPS.

In another example, the ASPS 102B is configured to automatically assign a receptacle to receive the corresponding power requirements for the sampled voltage. The ASPS 102B optionally may transmit the identification of the power requirements and the receptacle assignment to the computing device 506.

The ASPS 102B may have one or more power sampling connections, such as one or more power sampling receptacles or power connectors, including one or more AC and/or DC receptacles and/or other connections. When an electrical device 508 is plugged into or otherwise connected to the power sampling receptacle, the ASPS 102B samples the power requirements (including voltage and/or current) of the electrical device.

FIG. 6 depicts another exemplary embodiment of an APS 502A. In this embodiment, the electrical device 506A includes an AS processing system. In the embodiment of FIG. 6, power is transmitted from the ASPS 102C to the electrical device 506A. Additionally, data is communicated between the ASPS 102C and the electrical device 506A.

It will be appreciated that the power and the data may be transmitted over the same physical connection, one physical connection for the power and another physical connection for the data, or multiple physical connections for the power and/or data.

In one embodiment of FIG. 6, the ASPS 102C identifies that an electrical device 506A has been plugged into one of the receptacles. This identification may be made through hardware, software, firmware, or other methods. In one example, the electrical device 506A makes a circuit when the electrical device is plugged into the receptacle. In another example, the electrical device 506A causes the receptacle to transmit a signal when the electrical device is plugged into the receptacle.

In one example, the electrical device 506A generates a power request upon being connected to the receptacle. In one example, the request includes an identification of the particular electrical device. In another example, the request includes specific power requirements for the electrical device 506A.

The ASPS 102C receives the request and determines the power requirements for the electrical device 506A. In one example, the ASPS 102C identifies the particular electrical device 506A and searches its data, such as through a look up, a search, or other determination, to identify the power requirements for the electrical device 506A. The ASPS 102C provides the appropriate power, including the appropriate voltage and amperage, to the electrical device 506A.

In another example, the ASPS 102C receives a request for power from the electrical device 506A. In this example, the request includes the specific power requirements. In this example, the ASPS 102C is not required to perform a look up, search, or other determination to identify the power requirements for the electrical device 506A. The ASPS 102C provides the power to the electrical device 506A according to the power requirements.

In another example, the ASPS 102C has one or more power sampling connections, such as one or more power sampling receptacles or power connectors, including one or more AC and/or DC receptacles and/or other connections. An electrical device 506A is plugged into or otherwise connected to the power sampling receptacle of the ASPS 102C. The ASPS 102C samples the power requirements from the electrical device 506A. The ASPS 102C assigns an AS DC receptacle to which the required power will be generated and generates the required power to the assigned AS DC receptacle.

The AS processing system 702 also may transmit data and/or other communications to the electrical device 506B via the AS communication interface 706B.

In one embodiment, the AS processing system 702 controls conversion of power at the power converter 708. In one example, the AS processing system 702 transmits control signals to the power converter 708 to control the power conversion and subsequent output of the converted power to one or more receptacles. In another example, the AS processing system 702 is configured to control at which receptacle the power is output from the power converter 708. For example, the AS processing system 702 may transmit a control signal to the power converter 708 requiring the power converter to output power to a selected receptacle. In another example, the power converter 708 is hard wired to one or more receptacles, and the AS processing system 702 controls hard wired switches from the power converter to one or more receptacles. In another example, the power converter 708 may otherwise output power to particular receptacles in response to control signals from the AS processing system 702.

The AS processing system 702 also controls power sampling, processes signals indicative of sampled power, controls and/or manages assignments of receptacles for power sampling, and controls and/or manages generating power to one or more receptacles for the sampled power. The ASPS 102D has one or more power sampling connections from which power is sampled, such as one or more power sampling receptacles or power connectors, including one or more AC and/or DC receptacles and/or other connections. Signals from these power sampling connections are transmitted to the AS processing system 702 for processing. Based on processing one or more of the power sampling signals, the AS processing system 702 determines the power requirements controls generating power for the power requirements to a selected receptacle.

In one example, the electrical device 506C is connected to a power sampling connection of the ASPS 102D. The ASPS 102D samples the power requirements from the electrical device 506C. The processing system 702 processes the sampled power and determines the power requirements for the electrical device. The processing system 702 selects a DC receptacle to which the required power will be generated and generates one or more control signals to the power converter 708 requiring the power converter to generate power to the selected receptacle. In one example, the processing system 702 receives signals indicative of the sampled voltage, processes the signals, and determines the power requirements for the electrical device 506C.

The power converter 708 receives power from the power input interface 710. The power input interface 710 receives power from the electrical supply 504.

In one example, the power control/indicators may indicate that power is enabled or disabled for a particular receptacle based upon power being transferred to the control/indicator. Other examples exist. In another example, the power control/indicator is a physical switch used to disable or enable power to a particular output, regardless of any control processing by the AS processing system 702.

The AS processing system 702 also may transmit data to, and receive data from, a computing device 508B or another device via the communication interface 714. The communication interface 714 may be used to transmit and/or receive control data, configuration data, status data, or other data. In one example, the AS processing system 702 transmits and/or receives configuration data from the computing device 508B via the communication interface 714. In another example, the AS processing system 702 transmits and/or receives configuration data from the computing device 508B via the communication interface 714 and stores the configuration data in the storage device 704. The configuration data may be, for example, search data or other data used by the AS processing system 702 to identify power requirements for one or more electrical devices.

The AS processing system 702 also may transmit and/or receive other data, such as communication data, application data, video, voice communications, and other communications via the communication interface 714 to the computing device 508B or through the electrical supply 504. In one example, the electrical supply 504 includes a power supply grid.

In one example, the UI enables a user to configure particular receptacles on the ASPS 102D for particular electrical devices. The UI presents a simple screen or other output to the user, such as with radio buttons, check boxes, or drop-down boxes to enable or to disable particular receptacles or make selections. Text boxes enable a user to enter data, such as voltage and/or current values and names of electrical devices, other identifiers, and other text. For example, a user may use the UI to program a DC receptacle for a mobile telephone by setting the voltage and/or amperage requirements of the mobile telephone for a selected receptacle. The user may use the GUI to program a second DC receptacle for a PDA by setting the voltage and/or amperage requirements of the PDA for a selected receptacle. In a particular embodiment of this example, the user may select an identification of the electrical device from a menu or other interface. The electrical device then may be assigned to a particular receptacle. Alternately, the user may enter the name or other identifier of the electrical device.

In another example, the particular receptacle with the associated electrical device may be enabled or disabled using a radio button, check box, or other entry on the UI. In the above example, after the user configures the first receptacle for the mobile telephone, an enable and disable button is generated for the first receptacle.

FIG. 10 depicts an exemplary embodiment of an ASPS 102G. In the embodiment of FIG. 10, a processor 1002 controls the operation of the ASPS 102G.

Power is received at the ASPS 102G from a power system 416. In the embodiment of FIG. 10, the power is received at a fuse 1004. In other embodiments, the power may be received into the ASPS 102G at a resetable switch 1006, at an on/off switch 1008, or at another component.

In the embodiment of FIG. 10, the fuse 1004 enables power to flow from the power system 416 to the ASPS 102G. The fuse 1004 terminates the flow of power into the ASPS 102G when the amperage level or another power level reaches an upper limit. In one example, the fuse 1004 opens the circuit between the power system 416 and the resetable switch 1006, or other components of the ASPS 102G, if the resetable switch is not present or when the current from the power system 416 is approximately at or exceeds 30 amps, thereby terminating the flow of electricity to the ASPS 102G. In some embodiments, the fuse 1004 is replaced after the fuse opens the circuit between the power system 416 and the resetable switch 1006 or other components. The fuse 1004 is optional in some embodiments.

The resetable switch 1006 temporarily terminates the circuit between the power system 416 and the on/off switch 1008 or other components of the ASPS 102G if the on/off switch is not present.

The switch lead also is connected to the processor 1002, and a switch detector signal is transmitted via the switch lead to the processor. When the switch lead is connected to ground, the processor 1002 reads the switch detector signal as a logic 0, which corresponds to ground.

The name or other identifier may be assigned to or associated with a receptacle.

The power sampling system 1034 transmits sampling data or one or more signals to the processor 1002. The sampling data or signals indicate the sampled power requirements.

The processor 1002 controls the operations of the ASPS 102G. The processor 1002 controls the on and off states of the AC receptacles 1014 by enabling and disabling the optical relay 1010 to connect and disconnect the AC input power for output to one or more AC receptacles. The processor 1002 transmits one or more signals to the optical relay 1010 to make or break a connection for one or more of the AC receptacles 1014.

The processor 1002 controls the on and off states of the DC receptacles 1030. The processor 1002 controls which DC receptacles 1030 will be enabled with DC power. The processor 1002 determines the DC power level that will be output from the DC to DC regulator 1018 for each DC receptacle. The processor 1002 transmits a signal to the DC to DC regulator 1018 identifying the DC power level to be output to each DC receptacle and enables the DC power output level for that DC receptacle.

The processor 1002 processes the sampling data or signals from the power sampling system 1034. The processor 1002 then determines the power requirements for the electrical device based on the sampling data or signals. For example, the sampling data or sampling signals could be a lower value DC signal. The value of the signal corresponds to the value required by the electrical device.

The processor 1002 controls the transmission and reception of data to and from the modulator 1020. The processor 1002 receives data from the modulator 1020 and processes the data. The data may include, for example, a specific or approximate DC voltage level required by an electrical device connected to one of the DC receptacles 1030 and/or an identification of the electrical device.

The processor 1002 determines the type of communication that will be made via the modulator 1020. In one example, the processor 1002 controls the modulation of the modulator 1020 so that communications are made in a format receivable by the electrical device connected to the DC receptacle 1030. The processor 1002 also controls demodulation of the modulator 1020 so that communications received from an electrical device are transmitted in a format receivable by the modulator 1020 and processable by the processor 1002.

The processor 1002 controls the indicators 1024. The processor 1002 transmits one or more signals to one or more of the indicators 1024 for an indicator status.

The processor 1002 processes communications received via the modulator 1020 and the communication system 1028. The processor 1002 also transmits communications via the modulator 1020 and the communication system 1028.

In one embodiment, the processor 1002 generates a user interface via the communication system 1028 for display, such as for display on a computer system with a monitor. In this embodiment, the processor 1002 transmits data to the computer system for display. The data may include, for example, voltage levels required for a particular DC receptacle 1030, power sampling data, instructions to enable a particular DC receptacle for a particular level, instructions to assign power values to one or more receptacles, instructions to sample a receptacle, instructions to enable or disable one or more AC receptacles 1014 and/or DC receptacles 1030, or other data.

In another embodiment, the user interface resides on a computer system that is communicating with the processor 1002 via the communication system 1028 and the communication interface 1032. In this embodiment, the processor 1002 transmits data to the computer system for display by the user interface. The computer system transmits data received from the user interface to the processor 1002 for processing. In this example, the data may include, for example, voltage levels required for a particular DC receptacle 1030, instructions to enable a particular DC receptacle for a particular level, instructions to enable or disable one or more AC receptacles 1014 and/or DC receptacles 1030, or other data.

In one embodiment, the processor 1002 monitors the output from the DC to DC regulator 1018 to identify the actual or approximate actual voltage being generated from the DC to DC regulator to a selected DC receptacle 1030. The raw analog voltage level generated by the DC to DC regulator 1018 is used as a feedback signal and is input back to the processor 1002. This feedback signal is indicated by the dashed-line between the processor 1002 and the DC to DC regulator 1018 in FIG. 10. In this embodiment, the processor 1002 has a voltage divider that divides the feedback signal to a lower DC voltage range, such as between 0 volts and 5 volts, samples the divided feedback signal with an analog-to-digital converter, and uses the sampled feedback signal to determine if any adjustments must be made to the output of the DC to DC regulator 1018 to maintain the proper output DC voltage. In one example, the voltage divider is a circuit having two resistors.

In one embodiment, the processor 1002 transmits an adjustment signal to the DC to DC regulator 1018 to adjust its output of a DC voltage for a particular DC receptacle 1030. In one example, the adjustment signal is an analog output signal that is used to inject an offset into the DC to DC regulator 1018. In this example, the degree of offset is linearly related to the output DC voltage of the DC to DC regulator 1018. This voltage may be expressed as Voutput=Vadjustment*Beta, with Beta=GainFactor+Tolerance. The GainFactor is a gain specific to the DC to DC regulator 1018, and its value depends upon the exact design of the DC to DC regulator. The Tolerance is a parameter used to express the production tolerance of each DC to DC regulator. Ideally, the Tolerance is 0.

The feedback loop signal enables the processor 1002 to vary Vadjustment until Voutput is equal to the DC voltage required by the electrical device connected to the particular DC receptacle. In other embodiments, the adjustment signal includes a raw digital format, rather than an analog format. Other examples exist.

In one embodiment, when an electrical device is connected to one of the DC receptacles 1030, the processor 1002 causes a minimal level of DC power to output from the DC to DC regulator 1018 to the DC receptacle. The minimal power level is enough DC power to initiate operations of the electrical device, such as operation of the electrical device's processor, but not enough DC power to fully power the electrical device. The minimal power level is low enough that it will not exceed power levels that may damage the electrical device. In this example, the minimal power level enables the processor of the electrical device to communicate with the processor 1002 of the ASPS 102G. The processor of the electrical device then is able to transmit the voltage requirements or the electrical device's identification to the processor 1002 of the ASPS 102G. The processor 1002 then configures the DC voltage level to be output from the DC to DC regulator 1018 to the DC receptacle 1030 in which the electrical device is connected and enables output of the DC power to that DC receptacle.

FIG. 11 depicts another exemplary embodiment of a ASPS 102H. In the embodiment of FIG. 11, the ASPS 102H includes DC receptacle 1 1030A through DC receptacle N 1030B. Each DC receptacle 1030A-1030B has an associated detector 1102-1104, such as a detector switch for the barrel connector described above. Other examples exist. Each detector 1102-1104 is configured to enable a signal to the processor 1002A identifying that an electrical device connector has been connected to the receptacle 1030A-1030B.

A modulator 1020A-1020B is configured to communicate between a respective DC receptacle 1030A-1030B and the processor 1002A. The processor 1002A transmits communications to the DC receptacles 1030A-1030B via the modulator 1020A-1020B and receives communications from the DC receptacles via the modulators.

A low current driver 1106 and 1108 and a high current switch 1110 and 1112 are associated with each DC receptacle 1030A-1030B. The low current drivers 1106 and 1108 receive DC power from the DC to DC regulator 1018A-1018B at a low current level and/or a low voltage level. The low current drivers 1106-1108 provide the DC power to the DC receptacles 1030A-1030B. The low current driver 1106-1108 is used to signal to the electrical device connected to the DC receptacle 1030A-1030B that the processor 1002A will transmit communications to, or receive communications from, the electrical device. In one embodiment, a low current driver 1106-1108 includes one or more resistors.

The high current switches 1110-1112 receive DC power from the DC to DC regulator 1018A-1018B at a high current level and/or a high voltage level. The high current switches 1110-1112 provide the DC power to the DC receptacles 1030A-1030B. The DC power provided by the high current switch 1110-1112 to the DC receptacle 1030A-1030B is used to charge or otherwise power the electrical device connected to the DC receptacle. In one embodiment, a high current switch 1110-1112 includes a transistor or multiple transistors configured to receive DC power from the DC to DC regulator 1018A-1018B and to receive an enable signal from the processor 1002A. Upon receiving the enable signal from the processor 1002A, the high current switch 1110-1112 transmits the DC power to the DC receptacle 1030A-1030B.

In the embodiment of FIG. 11, the processor 1002A and the modulators 1020A-1020B are configured to communicate using voltage modulation. In one embodiment, the modulator 1020A-1020B transmits communications to, and receives communications from, the DC receptacle 1030A-1030B using a hexadecimal format. In one example, one or more communications transmit ASCII-based characters using hexadecimal format.

In one embodiment, the ASPS 102H of FIG. 11 operates as follows. The DC receptacle 1030A includes a female barrel connector having a ground pin, a power pin, and a switch pin. The detector 1102 is the switch pin and switching mechanism in this example.

When a mating jack is not connected to the DC receptacle 1030A, the switching mechanism causes the switch pin to be connected to the ground lead. The switch pin also is connected to an input of the processor 1002A. When the switch pin is connected to ground, the processor reads the switch pin signal as a logic 0, which corresponds to ground.

An electrical device having a male connector is plugged into the DC female barrel connector receptacle. When the device is connected, the switch lead of the detector 1102 is disconnected from the ground lead. In this example, pull-up resistors are connected to the switch lead between the detector 1102 and the processor 1002A. When the switch lead is disconnected from ground, the detector signal transitions to a logic 1.

When the detector signal transitions to a logic 1, the processor 1002A determines that an electrical device is connected to the DC receptacle 1030A. The processor 1002A causes a low current and/or a low voltage driver signal to be generated from the DC to DC regulator 1018A through the low current driver 1106 to the DC receptacle 1030A. In this example, the low current signal is 24 volts DC and less than 5 milli-amps. The low current signal is enough power to turn on a processor for the electrical device. However, the low current signal likely does not have sufficient amperage to damage the electrical device.

The low current driver signal is an indication to the electrical device that one or more communications will be transmitted from the ASPS 102H to the electrical device. The processor 1002A transmits a query to the electrical device through the modulator 1020A and to the DC receptacle 1030A. In this example, the modulator 1020A uses voltage modulation to transmit the communication.

After the low current driver signal has been transmitted to the electrical device, the processor 1002A causes the modulator 1020A to transmit the communication to the electrical device through the DC receptacle 1030A. In this example, the processor 1002A transmits a series of enable and disable signals to the modulator 1020A. In response to the enable signals, the modulator 1020A outputs a voltage having an amplitude greater than a minimal amperage, such as 3 volts DC. The electrical device receives the voltage having the amplitude and recognizes it as a logic 1. When the modulator 1020A receives a disable signal, the modulator either outputs a voltage having a level below the minimal level or does not output any voltage at all. The electrical device identifies that the voltage is either below the minimal level or that no voltage is received at all and reads this as a logic 0. Using this method, a series of 1s and 0s are transmitted between the modulator and the electrical device as one more data packets.

The electrical device transmits a communication to the modulator 1020A through the DC receptacle 1030A, and the modulator transmits the communication to the processor 1002A. In this example, the processor 1002A has a divider circuit that divides the voltage of the communication to a lower voltage, such as voltage between 0 and 5 volts DC. The processor 1002A also has an analog-to-digital converter that samples the divided communication. The processor 1002A reads the converted signal and identifies the communication type and the data in the communication.

In this example, the communication from the electrical device is an acknowledgment indicating a status OK command. The processor 1002A transmits a message via the modulator 1020A requesting a voltage code and an identification string from the electrical device. The processor 1002A receives a communication from the electrical device via the modulator 1020A with the voltage code and the identification string for the electrical device.

The processor 1002A transmits a signal to the DC to DC regulator 1018A for the requested voltage and enables the output from the DC to DC regulator to the high current switch 1110. The processor 1002A also enables the switch for the high current switch 1110, which causes the DC power to flow from the DC to DC regulator 1018A through the high current switch 1110 and to the DC receptacle 1030A.

If the processor 1002A communicates with the electrical device while or after the electrical device receives the DC power generated from the DC to DC regulator 1018A through the high current switch 1110, the processor 1002A disables the output from the DC to DC regulator to the high current switch 1110. The processor 1002A may accomplish this by disabling the output from the DC to DC regulator 1018A, disabling the high current switch 1110, or both.

The processor 1002A then enables a low current and/or low voltage driver signal from the DC to DC regulator 1018A to the low current driver 1106. The low current driver 1106 transmits the low current driver signal to the electrical device through the DC receptacle 1030A. The low current driver signal is a signal to the electrical device that a communication will be transmitted from the processor 1002A. In this example, the processor 1002A and the electrical device operate in a master-slave relationship. In other embodiments, a polling relationship may occur between the processor 1002A and the electrical device. Other examples exist.

After the low current driver signal has been transmitted to the electrical device, the processor 1002A causes the modulator 1020A to transmit the communication to the electrical device through the DC receptacle 1030A. In this example, the processor 1002A transmits a series of enable and disable signals to the modulator 1020A. In response to the enable signals, the modulator 1020A outputs a voltage having an amplitude greater than a minimal amperage, such as 3 volts DC. The electrical device receives the voltage having the amplitude and recognizes it as a logic 1. When the modulator 1020A receives a disable signal, the modulator either outputs a voltage having a level below the minimal level or does not output any voltage at all. The electrical device identifies that the voltage is either below the minimal level or that no voltage is received at all and reads this as a logic 0. Using this method, a series of 1s and 0s are transmitted between the modulator and the electrical device as one or more data packets.

Similarly, in this example, the electrical device transmits one or more data packets to the modulator 1020A having a voltage amplitude that indicates a logic 1 or a logic 0. The voltage levels are transmitted from the modulator to the divider circuit and the analog-to-digital converter on the processor 1002A and read by the processor as a logical 0 or a logical 1.

FIGS. 23-58 depict an exemplary embodiment of a user interface (UI) 2302. The UI enables a user to determine if an electrical device is connected to the ASPS. In the embodiment of FIGS. 23-58, an electrical device is referred to as an automatic sensing-direct current and automatic synchronous-data communication (asDC) device, and the ASPS is referred to as an intelligent power hub.

The UI enables a user to select the voltage to be transmitted from the ASPS to an electrical device and to select the DC receptacle to which it will be generated. The UI also enables a user to turn one or more AC receptacles and/or DC receptacles on or off. The US also enables the operation of the power sampling system, including initiating power sampling, setting automatic sampling, selecting a DC receptacle for a sampled voltage, setting an automatic assignment for assigning a DC receptacle to a sampled voltage, entering a name or identifier for a sampled device, assigning voltages to one or more receptacles, and enabling/disabling one or more receptacles. For exemplary purposes, the UI of FIGS. 23-43 is directed to only one AC receptacle (identified as an AC port on the UI) and only one DC receptacle (identified as a DC port on the UI), and the UI of FIGS. 44-58 is directed to multiple AC receptacles (ports) and multiple DC receptacles (ports). However, other UIs may enable selection of one or multiple AC receptacles and one or multiple DC receptacles.

Additionally, a computer is connected to the power hub through a USB connection in an embodiment of FIGS. 23-58. The UI in this embodiment is generated through the host computer and displayable on the computer's display. Other examples exist.

In one example, when the computer is not connected to the power hub, the UI indicates that no power hub is connected to the computer and no asDC device is connected to the power hub, as depicted in FIG. 23. When the power hub is connected to the computer, the UI indicates that the power hub is connected to the computer via the USB port, as depicted in FIG. 24.

As depicted in FIG. 25, when an asDC device is connected to the power hub, a window is displayed with the status change. The user selects the “OK” button on the status change window, and the status change window disappears. In other embodiments, the status window briefly appears and automatically disappears after a selected period of time. The asDC device status indicates that an asDC device was identified, as depicted in FIG. 26. The asDC device identification is specified by values in two fields, including a name or identity field and an operating voltage field. In the example of FIG. 26, the name or identity field may contain a string of up to forty characters. In this example, the device is identified as an “asDC Motorola 730” having an operating voltage of 5.29 volts DC. Other examples exist.

When the asDC device is disconnected from the power hub, a status change window is generated, as depicted in FIG. 27. The device status indicates that no asDC device is connected to the power hub, as indicated in FIG. 28.

An electrical device that is not configured to communicate with the power hub is referred to as a non-asDC device. If a non-asDC device is connected to the power hub, a status change window indicates that the non-asDC device is connected to the power hub, as indicated in FIG. 29. The status change window suggests that the user manually enable a DC receptacle.

The user may select a voltage to be output to a selected DC receptacle, as depicted in FIG. 30. In this example, the user selected the voltage level to be output to the selected DC receptacle. The user then selected the “force asDC port ON” to set the DC receptacle to the selected voltage level.

The user may elect to turn the AC receptacle on or off, as depicted in FIG. 31. If the user selects the check box for “AC port on/off,” the user may turn the receptacle on and off. When the AC receptacle is turned on, the power hub status window indicates that the AC port was enabled.

If the user again selects the check box for the AC port on/off, the AC power for the AC receptacle is turned off. The check mark from the check box disappears, and a new line is entered for the power hub status indicating that the AC port is disabled, as depicted in FIG. 32.

As depicted in FIGS. 33-34, the user turns the power on for the DC receptacle. In this example, the user selects a different voltage to be output to the DC receptacle. The user then selects the “force asDC port ON” check box. A check mark appears in the check box to indicate that the power is being transmitted to the DC receptacle. In addition, a line appears in the power hub status indicating that the DC port was forced on, as depicted in FIG. 34. In this example, the status line also indicates the code for the voltage and/or the device name.

The user may select the check box for the DC port again to force the DC receptacle off, as indicated in FIG. 35. A status line is generated to the power hub status indicating that the DC port was forced off.

The UI enables the user to update the firmware on the power hub, as indicated by FIG. 36. The UI enables the user to select from an open firmware option and a download firmware option. The open firmware option may be used to locate a file that is to be installed, as indicated in FIG. 37. The user selects the file to be opened, and the contents of the file are checked for integrity. If the integrity check is successful, an integrity check window appears and identifies the firmware as being valid, as indicated in FIG. 38. When the user selects the “OK” button from the integrity check status window, the firmware is opened and downloaded.

If the user selects the download firmware option from the display of FIG. 36, a status change window is generated indicating that the firmware download is starting, as depicted in FIG. 39. If the download process is successful, a status change window is generated indicating that the download is complete, as depicted in FIG. 40.

When the firmware has been downloaded, the user may select the reset on the power hub or cycle the power supply for the power hub by disconnecting the power supply from the power hub and reconnecting it. The user may relaunch the UI if desired.

A third option from the advanced menu option from FIG. 36 enables a user to change a target configuration of an asDC enabled device. When the user selects the change target configuration option from the menu, an update target properties window is generated for display, as depicted in FIG. 41. The user enters new values for the asDC device name and its operating voltage, as depicted in FIG. 42. When the asDC device is connected to the power hub, the power hub recognizes the device and its required operating voltage, as depicted in FIG. 43.

FIGS. 44-58 depict examples of user screens for a power sampling system. In the example of FIG. 44, four AC receptacles (ports) and one four DC receptacles (ports) are identified for operation and control. Each port has an associated check box for selecting that port. Once selected, the port may be assigned a power level, force to a power level, or enabled or disabled.

The UI also includes a status window or frame for identifying the status or operations of the system. Operations of the power sampling and logging is generated to the status frame. Operations of the automatic sensing and other functions of the system also are generated to the status frame.

The UI may include one or more selection or operation buttons for initiating an action or operation. Some embodiments include a Sample Port button that initiates the power sampling operation for one or more power sampling ports. Some embodiments include a separate Sample AC Port for sampling one or more AC receptacles and a separate Sample DC Port for sampling one or more DC receptacles. A Read asDC Voltage (Volt) button initiates communication between the ASPS and the electrical device to determine the power requirements for the electrical device. An Assign Port button assigns a sampled power or an AS DC determined voltage to a particular selected port. A Force Port button forces a selected port on or off The Force Port button also forces a selected DC port to a power value entered in the entry box.

An Auto Sample check box enables and disables an automatic (auto) sample feature configured to automatically detect and sample power requirements for a device, including a transformer, connected to a power sampling receptacle. An Auto Assign button enables and disables an automatic assignment feature that automatically assigns a sampled power to a default receptacle (port), such as the next lowest numbered receptacle. An ASDC Device Status frame shows the AS DC determined voltage and a name for the AS DC determined device. A Power Box shows the sampled power. An entry box, drop down box, or other entry mechanism enables a user to enter a name or other identifier for a power sampled device. The name or other identifier may be assigned to a receptacle (port) with an Assign Name button or other button or operation.

FIGS. 44-46 depict an exemplary embodiment of user interface screens having a separate Sample DC Port and Sample AC Port buttons. In this example, the system is ready to sample power requirements of an electrical device, as depicted in FIG. 44. The user selected the Sample AC Port button, and the system samples the power requirements of the electrical device. The power requirements are shown in the Power Box as 5.3 volts DC (VDC), the user selects the check box for DC Port 2 to receive the power requirements identified by the sampled power, and the Status Frame indicates the user selected DC Port 2 to receive power required for the sampled power, as depicted in FIG. 45. The user selects the Assign Port button, DC Port 2 is assigned 5.3 VDC as its output power, and the Status Frame indicates DC Port 2 was assigned the sampled power, as depicted in FIG. 46.

In the example of FIG. 46, once the selected DC port is assigned for output of power requirements, the name of the port is grayed out to indicate it is assigned or in use. Similarly, if an AC port is forced off, the name of the AC port is grayed out to indicate it is off. Therefore, in the example of FIG. 46, after the DC Port 2 is assigned, the name of DC Port 2 is grayed out to indicate it is assigned. DC Port 3 already was grayed out to indicate it was assigned. AC Port 1 is grayed out to indicate it is off. These features are optional. Other features may be used to indicate a port is off, on, assigned, or in use. Alternately, such features are not used.

FIGS. 47-49 depict an exemplary embodiment of user interface screens having a single Sample Port button, a Power Box to show the sampled power, an Auto Sample button, an Auto Assign button, an Entry Box to enter the name or identifier of the sampled device, and an Assign Name button to assign the entered name or identifier to the DC Port selected to receive the sampled power. In this example, the Auto Sample and Auto Assign options are not selected.

As depicted in FIG. 47, the user selected the Sample Port button, and the system samples the power requirements of the electrical device. The power requirements are shown in the Power Box as 4.2 VDC, the user selects the check box for DC Port 2 to receive the power requirements identified by the sampled power, the Status Frame indicates the user selected DC Port 2 to receive power required for the sampled power.

DC Port 2 is assigned the name or identifier of LG Phone, and the Status Frame indicates DC Port 2 was assigned the name LG Phone.

FIGS. 48 and 49 depict optional examples of name or identifier assignments for ports. In the example of FIG. 48, the name or identifier assigned to DC Port 2 is displayed when the user places the pointer over the DC Port 2 identifier, such as with a mouse, pointer, or other device. In the example of FIG. 49, the identifier for DC Port 2 is replaced by the name LG Phone, which is the identifier assigned to DC Port 2. The name DC Port 2 is displayed when the user places the pointer over the name LG Phone.

FIGS. 50-51 depict an example of un-assigning a DC Port. In these examples, a DC Port was assigned a sampled voltage or an AS DC determined voltage, and the user un-assigns that port. As shown in FIG. 50, the user selects assigned DC Port 3, and the Status Frame indicates DC Port 3 is selected. As shown in FIG. 51, the user selects the Force Port button, the Status Frame indicates that DC Port 3 is unassigned, and DC Port 3 is no longer grayed out.

FIGS. 52-53 depict an example of the Auto Sample and Auto Assign features. As shown in FIG. 52, the Auto Sample and Auto Assign features are selected and on. As indicated in the Status Frame, the system detects a device connected to a power sampling receptacle, samples the device, determines the device requires 5.3 VDC, automatically selects the first open DC Port (DC Port 1), and assigns the sampled power to the selected DC Port. Another default selection and assignment may be used.

FIG. 62 depicts an exemplary embodiment of a power sampling system 1034D. An AC power sampling receptacle 6002 receives AC power. A DC receptacle 6102 receives DC power. An AC/DC converter 6004 converts the received AC power to a DC power level. Optionally, the AC/DC converter may transmit the converted AC/DC power to the DC/DC converter 6104 for further down conversion. Otherwise, the AC/DC converter transmits the converted power to a detector 6006. The DC receptacle 6102 transmits the DC power to a DC/DC converter 6010 for further down conversion. The DC/DC converter 6010 down converts the DC power to a lower DC power level and transmits the lower DC power level to the detector 6006. The detector 6006 detects various power levels of the DC signals and transmits the various power levels to the processor 1002D. The processor 1002D receives the DC signals from the detector 6006 indicating the various power levels and determines the power levels corresponding to the sampled power requirements.

FIG. 63 depicts an exemplary embodiment of a power sampling system 1034E. A power sampling receptacle 1036 receives the power to be sampled. A rectifier 6302 converts the received power to a DC value signal, a filter 6304 smoothes the DC signal, an operational amplifier 6306 converts the voltage to a lower DC value, and the processor 1002E processes the received value. Since the operational amplifier 6306 converts the DC signal by a known factor, the signal received by the processor 1002E is a known factor.

The processor 1002C receives the DC signals from the detector 6006 indicating the various power levels and determines the power levels corresponding to the sampled power requirements.
